s IMPROVEMENT |N sHiNGLE-MACHINES.

Specification forming part of Letters Patent No. 150,480, dated May 5,1874; application filed i February 28, 1874.

To all whom it may concern:

Be it known that L'SrENoER B. PEUGH, of

"Salem, in the county of Washington and State of Indiana, have inventeda new improvement in ShingleLMachines for sawing shingles, of which thefollowing is a specification:

In the accompanying drawing, Figure 1 represents a top View of myattachment to sawmill carriage for sawing shingles; Fig. 2, a verticaltransverse sect-ion of the same on the line c c, Fig. l; and Fig. 3, adetail side View of block, showing manner of cutting the shingles, withalternating butts and points.

Similar letters of reference indicate corresponding parts.

The invention will first be fully described, and then pointedout in. theclaim.

A in the drawing represents a carriage of the usual construction, formoving the log against the circular saw. To the outermost lateral head-hloeks B of the carriage ,are hinged lever-rods C, which turn onpivot-pins a, placed nearly levelwith. the top of blocks B. Rods Cextend sidewise along the headblocks, and connect at the rear ends, by pivoted links b, with a longitudinal crank-rod, d, which is supported instaples or hinges c ot' the side piece of the carriage, and turned bymeans of a hand-lever, f, at one or both sides. Links I) are pivoted tothe arms of the cra-nkrod d at such a distance from the same that thelever-rods C may be thrown alternately into inclined position, asrequired, to feed the shingleblocks to the saw for obtaining thetapering shape of the shingles. The position of lever f is changed afterthe carriage has passed the saw, and retained during the' time ofpassage by means of suitable rack or ratchet ,arrangement- Theblock'fastenin g frame D is guided, by railsg, along the lever-rods C,and moved toward and fromthe saw in the same manner as the logs. Theextent of motion of frame D is defined by bottom stops It, which come incontact with the pivot-pins a of the carriage, and rear stops h .ofhead-blocks B.

4from each block.

is then changed for the next trip by lever f, p

top jaws F are swung on the top of the blocks, v The top jaw.

and iirmly driven into the same. F is of U shape, as shown in Fig. 1,and has sharp teeth or spurs t', which enter into the block, and holdthe same iirmly in connectionl with the teeth of the lower jaws F.

The shinglefblooks are out from the log in the size of the shinglesrequired, iirmly attached to the block-fastening fra-ine D, and

fed, by the motion of the carriage, to the saw. Each trip of thecarriage cuts off a shingle The inclination of the block so thatshingles with alternating butt and point ends are cut from the blocks.The regular size of the shingles is then produced from the sections socut by ripping them to proper width by a smaller saw.

The blocks are cut oli' into shingles as fast as a log can be cut intoplanks, so-that shingles are thus produced, by a simple arrangement, outoi the whole blocks without any splittin g. u

The block-fastening frame maybe easily taken off when not required, andthe carriage then used for the ordinary purposes.

Having thus described my invention, I claim as new and desire to secureily-Letters Patent The d etachable shin gle-block-fastenin g frame D,constructed of recessed pieces D with projecting stationary bottom jawsF, and pivoted top jaws F', substantially as set forth.
